The 12AX7 is a miniature high-mu twin triode each section of which has an individual cathode connection. The Double Triode is especially suited for use in resistance-coupled voltage amplifers, phase inverters, multivibrators, and numerous industrial-control circuits where high voltage gain is desired. A center-tapped heater permits operation of the tube from either a 6.3-volt or a 12.6-volt heater supply.
